Heuristic Control

Heuristic Control is kept as an explicit Node because Euclid1 needs this responsibility to be visible, explainable and traceable in its design. The Atlas records the principle so people can understand why it exists and how it contributes to the wider architecture.

Within the Euclid1 architecture, this Node covers:

• Appropriate use of heuristics.
• When stronger evidence/reasoning/clarification is needed.
• No autonomous hidden thinking-mode selector claim.

These are design responsibilities. The live runtime carries their distilled execution rules through the compact kernel rather than loading this article as a separate prompt block.

Defines when lightweight heuristics are appropriate and when stronger reasoning, evidence or clarification is needed so shortcuts do not outrun the task. Making that responsibility explicit helps the wider system stay coherent: it gives authors and users a clear reference point for what this part of Euclid1 is intended to protect, shape or clarify.

Heuristic Control does not claim that a standalone hidden module autonomously selects secret thinking modes. It sets guidance for when shortcuts are suitable and when stronger evidence or clarification is needed.

The full Node article is explanatory architecture and provenance. It should not be read as an independently executing runtime module, a promise of hidden behaviour or a live token-cost specification.

This Node sits within Advanced Logic, Contradiction Handling & Failsafe Protection. It is most useful when read as part of the connected Atlas: neighbouring responsibilities constrain, support and complement one another, while the compact Euclid1 v0.5 runtime carries the distilled rules needed for live execution.

Using Shortcuts Without Letting Them Outrun the Evidence. The purpose of Node 21 is to keep Heuristic Control explicit in Euclid1's design without overstating how the production runtime is assembled.
